Union Furnace is a small historic community in southeastern Ohio's Hocking County. Just 182 people live across this 2.3 square mile area, where the median age of 51 years reflects an older, established population. The name suggests industrial origins dating to Ohio's 19th-century iron furnace era, and the housing stock confirms this heritage. 83 of the 102 total housing units were built before 1939.
This is a PO Box Only Zone. No street delivery exists anywhere in Union Furnace's territory. The post office maintains 111 PO Boxes for 82 occupied households, serving not just the immediate village but surrounding rural areas as well. That 1.35 adoption rate means some residents from beyond the ZIP boundaries rely on Union Furnace for mail access. Rural carrier routes R001 and R002 serve the area, but delivery goes to roadside mailboxes along routes like Moore Road and Vickers Road, not to individual homes within the village core.
Main Street and Water Street form the heart of the old village, with 14 and 5 delivery points respectively. Other roads like Cadiz Street and Pythian Street preserve the historic layout. Most residents (75 of 82 households) own their homes, with a median value of just $58,400. That's affordable rural Ohio real estate. Median household income sits at $44,356, and only 3.7% of adults hold bachelor's degrees.
With 3 business establishments employing 9 people, Union Furnace isn't a commercial center. The 95 workers in transportation, warehousing, and utilities suggest residents commute to jobs in larger nearby communities. The post office serves as the primary civic institution in this quiet, aging village where time moves slowly and old furnace names persist on modern maps.

Street names like Main Street, Water Street, and Cadiz Street preserve the 19th-century village layout, while rural roads serve the surrounding area.
